Hi JohnNada80,
I am Dave, I will help you with this.
If you are getting that 'Preparing Automatic Repair' screen, then your laptop is not booting form the USB.
If your screen is glitching in BIOS, that does indicate a hardware issue, who replaced the screen, was that Acer Support or a PC Repair Shop?
In BIOS if you can, ensure it is in UEFI Mode, disable Secure Boot and set the USB as the primary boot device.
Save those settings and then try booting from the USB again.
